Quite by accident but the timelines are matching nicely. OTL the FAA received its first Hellcats in March 1943 and HMS
Indomitable was the only RN fleet carrier to operate the type because Corsairs did not fit in her upper hangar so ITTL it would make sense that her fighter squadrons would take delivery of their new aircraft while training in the US with their carrier also getting a refit in the US -

Something else will be coming along later in 1943 for the FAA and the USN, Vought's Corsair. Just don't believe the stuff on the web about the Corsair's carrier service.
The Corsair's long nose was overcome by a banked approach to the carrier. It's landing gear stiffness and tendency to blow tires were the real stumbling blocks to it's carrier deployment. But they were quickly overcome by Vought.
Tom Blackburn, in his book "The Jolly Rogers" details that his squadron, VF-17 was due to be sent to the Pacific aboard
Bunker Hill (CV-17). They were to be the first carrier-borne Corsair squadron in the Pacific. They had received their first Corsairs in February 1943, and completed carrier quals aboard
Charger, a CVE.
VF-17 completed shakedown with
Bunker Hill on 10 August 1943, but was pulled at the last second after going all the way to Pearl Harbor with their carrier and replaced with VF-18 flying Hellcats VF-17 would have been the only Corsair squadron aboard the carriers and no supply line was in place to support them. (They were subsequently assigned to land bases with Marine Corsairs.) Blackburn makes it very clear in his book that this supply line concern was the reason the VF-17 did not join their carrier and had NOTHING to do with the planes characteristics. In fact, his men practiced carrier landings every time they approached a field.
As for the myth of the "FAA finally figuring out the Corsair" the FAA did not receive it's first Corsair until May, 1943. By that time, VF-17 was already using Corsairs and training with Charger, and was fully intended to be the first CV Corsair squadron. The first FAA operational squadron was 835 in August 1943, when/after VF-17 had already deployed for
Bunker Hill's shakedown.
Finally, I'd recommend Blackburn's book. He later went on to be skipper of Midway (CV-41).
